Answer 1

$\large\boxed{\begin{array}{l}\underline{\rm D\,\!efinic_{\!\!,}\tilde ao~de~potenciac_{\!\!,}\tilde ao}\\\sf a^n=\underbrace{\sf a\cdot a\cdot a\cdot a\cdot...a}_{n~fatores}\\\underline{\rm elementos~da~pot\hat enciac_{\!\!,}\tilde ao.}\\\sf a^n=b\\\sf a\longrightarrow base\\\sf n\longrightarrow expoente\\\sf b\longrightarrow pot\hat encia\\\sf o~expoente~nos~diz~quantas~vezes~devemos~repetir\\\sf e~multiplicar.\end{array}}$

$\large\boxed{\begin{array}{l}\tt a)~\sf 6^3=6\cdot6\cdot6=216\\\tt b)~\sf 3^2=3\cdot3=9\\\tt c)~\sf 5^3=5\cdot5\cdot5=125\\\tt d)~\sf 4^2=4\cdot4=16\\\tt e)~\sf 17^2=17\cdot17=289\\\tt f)~\sf 20^3=20\cdot20\cdot20=8~000\end{array}}$
